What is an 11kV distribution transformer?
An 11kV distribution transformer steps a medium-voltage 11kV supply down to the low voltage used by homes, commercial buildings, industrial plants and local distribution networks. The transformer is the core equipment; it can be supplied on its own or integrated with medium-voltage switchgear and low-voltage distribution equipment inside a packaged substation.
The 11 kV class covers most urban and rural distribution networks in Africa, the Middle East and South Asia, which is why it is the first range we publish prices for. Single unit or container load, the unit is the same: sealed corrugated tank, cold-rolled silicon steel core, full copper windings.
The three secondary voltages exist because different countries standardise differently — 400 V in most of Africa, 415 V in the UK-influenced grids, 433 V in parts of the Middle East. We build all three on the same platform, so the price does not change with the secondary voltage.
